3 out of 4 of your samples is corrupt, but this Noesis python script works with avatar.png.ckd

that file is zlib compressed instead of lzma, and it is headerless rgba32 when decompressed,
i will try to modify the script later to accomodate these best i can.
i might just put this into a Noesis python script later for fun.

edit: script updated in previous post

Is there a way to preserve the transparency when importing into Noesis, though? The transparency has been replaced with a black background. i'm pretty sure any image meant to have transparency in this game is accompanied by a file of the same name also with _a in the file name to denote "alpha...

here is Noesis python script to open pic files from this game.

i don't think these pic samples are apple formats, just typical paletted/non-paletted rgb images with pic extension.

they are lzma compressed, here is bms script to decompress to viewable dds files.

*updated script to support zlib compressed files also*

what is the full game name and the platform from which the samples came?
i don't think these are images, the data looks compressed to me, don't know.

i don't think removing the alpha is a good idea being that some rely on it but if you insist you can go into the script and change these lines: data = rapi.imageDecodeRawPal(data, palette, imgWidth, imgHeight, 8, "r8 g8 b8 a8") ... data = rapi.imageDecodeRawPal(data, palette, imgWidth, img...

i don't know what txd files you refer to, your first script posted looks incomplete and gets no results from your sample. the script i posted only finds and extracts each tex file from the sample, you still need to find a way to parse the tex files, this PS2 stuff has always been weird to me. :] edi...
